The two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase âeither cytosine (C), guanine (G), adenine (A), or thymine (T)âas well as a monosaccharide sugar called deoxyribose and a phosphate group.he two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides.

A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydroge â¦ n bonds between the base portions of the nucleotides hold the two chains together (Figure 4-3). As we saw in Chapter 2 (Panel 2-6, pp.
